Anti-counterfeit paper and its manufacturing method

Abstract

A security paper is provided with a security area; the security area is provided with at least two flaky anti-counterfeiting elements in series connection; the flaky anti-counterfeiting elements are connected successively through a hot melting and / or water-soluble material; in addition to certain machine-readable features, the flaky anti-counterfeiting elements also have black watermark effect; and the connecting part has white watermark effect. The invention solves the technical problem that watermarks formed by an anti-counterfeiting layer unit and a connecting line do not have obvious differences in the prior art, and provides a security paper capable of distinguishing the watermarks of the anti-counterfeiting layer unit and the connecting line, and having significant recognition feature; and the security paper is especially suitable for production of valuable documents, such as banknotes, passports and identity documents.

Description

technical field [0001] The present invention relates to an anti-counterfeit paper and a manufacturing method thereof, in particular to an anti-counterfeit paper used for producing valuable documents such as banknotes, passports, identity documents and the like. Background technique [0002] In the production process of security documents such as banknotes, securities, tickets, passports, certificates, etc., in order to improve their security performance, it is necessary to form a heterogeneous area on the paper used to produce these documents, which is called a heterogeneous area. The heterogeneous area is easy to identify, but not easy to imitate or counterfeit, thereby ensuring that the security document has a better anti-counterfeiting effect. Common methods include adding security threads, anti-counterfeiting labels, special fibers, and anti-counterfeiting sheets to paper. [0003] For example, in the patent application document with the application number 201010539764....

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the visual features of the anti-counterfeit layer unit and connecting line in the anti-counterfeiting paper in the prior art are not clearly distinguished, thus proposing a kind of anti-counterfeiting layer unit and connecting line that can present different watermark effects security paper
